LIFE-MOTION-PICTURE-PROJECTING MACHINE..

protecting the film from ignition and rendering access thereto easy.

. It consists primarily of a door hinged to lilrn carrying mechanism and connected to a lantern movable on ways so that when the lantern is in use the door is necessarily disposed between it and the film, and when moved out of posit-ion for use the door is opened thereby.

In the accompanying drawings, Figure 1 is a side elevation of a life motion picture projecting machine having my improvements applied thereto g Fig. 2 is an elevation of the door, and Fig. 3 is a plan view of the improvements, parts being omitted `for the purpose of illustration. i

As shown in the drawings, the stand 1 carries the lilm boxes 2, 3 and the film operating mechanism 4. A shoe 5 fixed on the stand by the clamp screw 6 supports the parallel Ways 7 which carry the lantern 8, the lantern having thereon the brackets 9 engaged to the ways so as to slide thereon.

A door 10 connected by the hinge -11 with the film operating mechanism is connected to the lantern by the link sections 12, 12 forming an adjustable link by means of the slots '12 therein and the clamp screw 12 passing through the slots, the link having the pivotal connection 13 lwith the door and the pivotal connection 14 with the lantern.

A shutter 15`is connected to the door by the hinge 16 so that it can be moved to open and close an aperture 17 in the door in ine with the lantern projecting tube S when in operative position. This shutter is operated by a lever 19 having the fulcrum connection 20 with the door and the link 21 havin@ the pivotal connection 22 with the lever and the pivotal connection 23 with the shutter.

When the lantern is in o eration, the door is positively closed and hel( between the projecting tube and the film, light passing through'the aperture in the door. When it Specication of Letters Patent.v Application filed May 3,1907. Serial No. 371,579.

l is necessary to have access to the film, the lantern is moved along the ways at right angles to the line of projection so that its tube is withdrawn from proximity to the film, the door being opened by the operation of withdrawing the lantern.

l When it is desired so to do, either the lanscrew 12 connecting the link sections.

Having described my invention, I claim 1. A magic lantern, a way on which said ilantern is adapted to move, a door, and

means connecting said door and lantern so tion said door is held thereby in the line of projection.

2. A lantern, a way on which said lantern is adapted to slide'transversely to its line of projection, a hin ed door, and a link connecting said door an lantern.

3. A lantern, means for supporting said lantern so that its tube can be thrown into and out of the line of projection, a ilm movking mechanism, and a door connected to said lantern so that when said lantern is in the projecting position said door is disposed in its line of projection .between it and the film moving mechanism. f

4. A lantern, a pair of ways extending transversely to the line of projection of said lantern, means whereby said lantern is movable on saidways into and out of the line of projection, a film moving mechanism, a door hinged' with relation to said film moving mechanism, and a link pivotally connected to said lantern and to said door.

5. A lantern, means for supporting said lantern so that it can be moved into and out of the line lof projection, a film movin mechanism,a door means connecting sald door with said lantern so that said door is held in the line of projection by said lantern when in the operative position, said door having an aperture therein in the line of projection, and means for openingand closing said aperture. In testimony whereof, I have hereunto set my name this 1st day of May, 1907, in the presence of the subscribing witnesses.
